Error Correction Mode (ECM) is an optional transmission mode built into Class 1
fax machines or fax modems. It automatically detects and corrects errors in the
fax transmission process that are sometimes caused by telephone line noise.
Emulation is a technique of one machine obtaining the same results as another.
An emulator duplicates the functions of one system with a different system, so
that the second system behaves like the first system. Emulation focuses on exact
reproduction of external behavior, which is in contrast to simulation, which
concerns an abstract model of the system being simulated, often considering its
Ethernet is a frame-based computer networking technology for local area
networks (LANs). It defines wiring and signaling for the physical layer, and frame
formats and protocols for the media access control (MAC)/data link layer of the
OSI model. Ethernet is mostly standardized as IEEE 802.3. It has become the most
widespread LAN technology in use during the 1990s to the present.
A suite of protocols developed by Apple Computer for computer networking. It
was included in the original Macintosh (1984) and is now deprecated by Apple
in favor of TCP/IP networking.
Foreign Device Interface (FDI) is a card installed inside the machine to allow a
third party device such as a coin operated device or a card reader. Those devices
allow the pay-for-print service on your machine.
A File Transfer Protocol (FTP) is a commonly used protocol for exchanging files
over any network that supports the TCP/IP protocol (such as the Internet or an
The part of a laser printer that fuses the toner onto the print media. It consists of
a heat roller and a pressure roller. After toner is transferred onto the paper, the
fuser unit applies heat and pressure to ensure that the toner stays on the paper
permanently, which is why paper is warm when it comes out of a laser printer.
